ABSTRACT
Ecological security and environmental sustainability are the foundations of sustainable development. With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem services. In this paper, considering the security of water resources, biodiversity conservation, disaster avoidance and protection and natural recreation, an integrated index of eco-space importance was established and a method for identifying key eco-space was created using GIS, with Lanzhou City, China as a case study. The results show that the area of core eco-space in the Lanzhou City is approximately 50,908.7 hm(2), accounting for 40% of the region's total area. These areas mainly consist of geological hazard protection zones and the core zones of regional river systems, wetlands, nature reserves, forest parks and scenic spots. The results of this study provide some guidance for the management of ecological security, ecological restoration and environmental sustainability.

ijerph-11-02550-f007: Evaluation results of natural recreation importance in Lanzhou City.

Mentions: From Figure 7 and Table 5, for natural recreation importance, the area of extreme importance is 4,688.425 hm2, accounting for 3.62% of the total area. These areas are mainly located in the mountains and the northwestern river systems and are made up primarily of the core areas of forest parks, such as the forest parks of Tulugou, Xujiashan, Shifogou and Lanshan, and scenic spots, such as the scenic spots of Zhufushan and Guantangou. The primary in these areas land use types are wetlands and woodlands, which have high values for natural recreation. This is mainly because, with the growing demand for outdoor recreation, wetlands and forests have become the residents’ recreational open space. The area of moderate importance is 6,289.425 hm2, accounting for 4.85% of the total area. The recreational value of these areas is quite high and they are distributed in the northwest mountains and the non-core area of the Xinglong Mountain Nature Reserve. We ought to control their capacity for tourists, avoid overexploitation from tourism, and maintain the natural landscape with high recreational value in these areas.

With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem services. In this paper, considering the security of water resources, biodiversity conservation, disaster avoidance and protection and natural recreation, an integrated index of eco-space importance was established and a method for identifying key eco-space was created using GIS, with Lanzhou City, China as a case study.
